Expand description

Optimization hint used in calculating change between two intermediate data.

Variants

Default

Don’t assume any optimization.

SizeSource

Put entire new object if change information size is greater than source (old) size.

SizeTarget

Put entire new object if change information size is greater than target (new) size.

SizeValue(usize)

Tuple Fields

0: usize

Bytesize threshold.

Put entire new object if change information size is greater than bytesize threshold.

SizePercentage(f64)

Tuple Fields

0: f64

Percentage threshold.

Put entire new object if change information size is greater than percentage of source size.
